AssetHub built an AI agent that recreates licensed characters in 3D while respecting copyright rules... But Jason says he needs to think BIGGER. 11 founders pitched their companies to Jason and Yuki Shirato of Techstars Tokyo at our Osaka event this week, and neither investor held back.

But here's why Yuki says the fear of failure is still holding back progress.
